株式会社ＳＣＲＥＥＮホールディングス

Resumen de: WO2025191937A1

In the present invention, a third catalyst that promotes the bonding of hydrogen and oxygen is disposed on the anode side of an electrolyte membrane (51). Even when hydrogen generated on the cathode side passes through the electrolyte membrane (51) and enters the anode side, the action of the third catalyst enables said hydrogen to bond with oxygen generated on the anode side, thereby converting into water. This makes it possible to reduce the concentration of hydrogen in the gas discharged from the anode side. Particles of the third catalyst have a hollow structure with a cavity therein. Therefore, the amount of the third catalyst used can be reduced while maintaining the surface area of the particles. Additionally, because the particles of the third catalyst have an opening, the movement of water, hydrogen, and oxygen at the anode side is less likely to be inhibited. Accordingly, reductions in the reaction rate of electrolysis on the anode side can be suppressed.
